A 13 might be different to my 16 which as stated above make lots of fuss if you try to leave it with the engine running. The walk away locking isn’t consistent enough to trust it and when I leave mine at work in the city centre, I sometimes get 100 yes away from it to go and check its locked and the windows are fully closed. Its a kind of “did I lock the front door” at home moment that comes from being a drip.
Never managed to leave the engine running I’m afraid though. It was actually parked up and not moving at the time? ;-)
